MEASURING INSTRUMENT.

Patented May 27, 1913.

Application filed January 22, 1918. Serial No.- 85 2,7601

To all whom it may concern:

Be it known that I, NILS Ham! Wm,-

a subject of the King of Sweden, and. a citizen' of Sweden, residing at 20- Norra Ban- .torget, Stockholm, Kingdom of Sweden,

have invented certain new and useful Im mvements in Measuring Instruments, of which the following is a specification.

Thepresent invention relates to measuringinstruments. and: especially recording and! registering instruments of that kind in which an organ moves a longer or shorter distance, which distancehas to be measured. In recording and registering instruments hitherto used the whole movement of said organ has been registered. In such instruments however, the disadvantage arose, that to 3. The difference in length of the indi= vid-ual lines will therefore obviously be threefold increased.

The particular embodiment selected for illustration of the invention is designated upon the basis of a recording machine, producing an inscription, from which can be read at any time, the positions assumed by the indicator during any measured interval of time; But the position of the indicator relatively to a surface graduated both as to the unit of measurement, and time is nevertheless: observable at all times, so that the measuring mechanism thus becomes a regis ter as well as a recorder.

The invention is illustrated on the accompanying drawings whereand Fig. 5' a detail'view of the indicator pulley.-

Fig. 1 shows a part of adiagram produced bymeans of the ordinary devices.

1 designates the whole length of the rag istering line drawn out from-line-Q;

Fig. 2 shows'a diagram produced accord ing to the present invention. Only the up per parts lying above the line AA of-the lines l'in Fig. 1 have been registered, these parts being for instance threefold -lengthened,"so that also the difference between-the different lines is threefold increased. Obviously a much closer observationmay thereby he carried out.

The apparatus shown in Figs. 3 and 4 wil l now be described. On the shaft a are arranged two pulleys b and c: The former one is made as a double disk, oarryingon theone side the bell D hanging from the re ed, in which bell for instance the volume s has to be measured, and on theother side of the pulley is suspended the counter weight e. The pulleycis not attached'to the shaft on but can turn-around said shaft and is for instance of a diameter thrice as large as that of the pulley b. The ulley'c carries the writing penf suspen ed from its periphery on a line cooperatingon its vertical reciprocating movement until the diagram 9. h designates a stationary inkholder with the' feeding tube a" with which the pen fcontacts when in its upper or sta tionasry position. The base line Gof the record on the diagrampaper corresponds to line A-A Fig. 2, to which the pen or index f always returns after each stroke. This diagram paper is ruled in the usual'ma-nner for reading oil from the base line. The unused paper is inserted as a roll at G from there the end of the paper is takenaround the drum G and fastened to the roll G on' which the diagram is wound-up. The drum G is continuously driven by a clockwork, thereby transferring the aper fromithe roll Gr to the roll G The c ockwork'is wound up by means of winding key G and'started 'or stopped by lever G The pu-liley a is balanced in the position shown in Fig. 3tby means of the reinforcement 0 and asmazll weight 0?, the latter being suspended from the *end of line f for the pen. The pulley b "is provided with an arm- 70 having a set screwl'and the pulley c' is provided with a projection m lying in the path of the set screw, see particularly Fig. 5. It is obvious that the pulley b by this arrangement can turn, the pulley 0, however, remaining still .until the set screw Z strikes against the projection m, the pulley 0 being thereby also rotated. By this means a dead course of the bell will be effected, and this first movement of the bell, which actuates the pulley b is consequently not recorded. This dead movement corresponds to the parts of the registering lines lying between'the lines 2 and A-A in Fig. 1. Only when the screw l strikes against the projection m will the pulley c, and with it the pen f be moved, said movement of the pen being thrice as great as the last part of the motion of the bell, as shown in Fig. 2. Fig 1 may be considered as a diagram of the whole motion of the driving bell and Fig. 2 as a diagram of the motion of the writing pen.

The driving bell D is of the usual construction and provided with a Water seal. The water is filled in through the funnel D communicating with the bottom of the bell housing. A three-way cock D is supplied near this bottom, through which the water may be filled in or drained 0E. The gas to be tested enters and leaves the bell through the pipe D, at certain intervals regulated by hand or automatically. Ob-

viously the bell may be replaced by any other measuring body for instance a column of liquid, a float or the like, as the device may be used for all kinds of measuring instruments, but especially for recording measuring instruments.

. comparatively great volume of the gas to be tested has to-be measured, the movement of a measuring body such for instance as the bell described above, being thereby recorded several times enlarged. If this movement were registered in its entire length the travel of the writing pen would be very great. The whole registering device then would occupy agreat deal of space. An additional advantage is that more precise readings may be obtained with my measuring instrument on account of the increase of the difierence between the recording lines of the diagram.

Having fully described my invention, what I claim and desire to protect by Letters Patent is 1. Recording mechanism consisting of a -movable measuring body, a movable recordmotion of the measuring body to the record ing organ after said body has'moved a predetermined distance uniform for every operation.

' 2. Recording mechanism consisting of a movable measuring body, an arm connected therewith, a projectin member cooperating with said arm ater said measuring body has moved a predetermined distance and a recording organ connected with said projecting member in such a way as to be givena greater motion than that of the projecting member.

3. Recording instrument consisting of a movable measuring body suspended from a pulley, an arm connected to said pulley, a second pulley mounted coaxially with said first pulley, a projection on the second pulley, said arm cooperating on the rotation of the first pulley with said projection, said second pulley bearing the recording organ and being of a greater diameter than the first pulley.

5. Recording instrument for measuring volumes comprising a movable measuring body, a balancing weight, a pulley from which said measuring body and said weight are suspended to balance each other, a sec- 0nd pulley balanced in a certain position, a common axis for both pulleys, a recording pen suspended from said second pulley and a diagram table adjacent to said pen, a set.
